Is a weight loss program based on exercise more effective than a program based on diet? The 44 overweight people put on a strict one year exercise program lost an average of 24 pounds with a standard deviation of 7 pounds. The 39 overweight people put on a strict one year diet lost an average of 22 pounds with a standard deviation of 11 pounds. What can be concluded at the 0.10 level of significance? Identify the course of action. [response1] Identify the correct parameter. [response2] Identify the number of populations. [response3] Identify the appropriate distribution. [response4]

Is there a difference in the proportion of wildfires caused by humans in the south and in the west? 495 of the 650 randomly selected wildfires looked at in the south were caused by humans while 331 of the 414 randomly selected wildfires looked at the west were caused by humans. What can be concluded at the 0.05 level of significance? A. H0: Psouth [eq] Pwest Ha: Psouth [neq] Pwest B. Test statistic: [response2] C. p-Value = [response3] D. Decision: [response4] E. Conclusion: There is [response5] evidence to make the conclusion that there is a difference between the proportion of wildfires caused by humans in the south and the proportion of wildfires caused by humans in the west.

Is there a difference in performance when students take exams alone or in a class setting. Eleven students were given two tests of equal difficulty? They took one test in a solitary room and they took the other in a room filled with other students. The results are shown below. Alone 88 74 94 65 75 79 86 81 70 77 90 Group 86 78 97 69 75 77 90 83 78 72 95 Assume the distribution of the differences is normal. What can be concluded at the 0.01 level of significance? (d = alone score – group score) A. H0: d [eq] 0 Ha: d [neq] 0 B. Test statistic: [response2] C. p-Value = [response3] D. Decision: [response4] E. Conclusion: There is [response5] evidence to make the conclusion that the population mean exam score differs based on whether students take the exam alone or around others.

The mayor is interested in finding a 95% confidence interval for the mean number of pounds of trash per person per week that is generated in city. The study included 120 residents whose mean number of pounds of trash generated per person per week was 31.5 pounds and the standard deviation was 7.8 pounds. Round your answers to TWO decimal places. A. To compute the confidence interval use a [response1] distribution. B. What is the margin of error (maximum error)? [response6] C. With 95% confidence the population mean number of pounds per person per week is between [response2] and [response3] pounds. D. If many groups of 120 randomly selected people in the city are studied, then a different confidence interval would be produced from each group. About [1-alpha] percent of these confidence intervals will contain the true population mean number of pounds of trash generated per person per week and about [alpha] percent will not contain the true population mean number of pounds of trash generated per person per week.

Are Republicans less likely than Democrats to display the American flag in front of their residence on the Fourth of July? 187 of the 400 Republicans surveyed display the flag on the fourth and 260 of the 500 Democrats surveyed display the flag on the Fourth of July. What can be concluded at the 0.10 level of significance? Identify the course of action. [response1] Identify the correct parameter. [response2] Identify the number of populations. [response3] Identify the appropriate distribution. [response4]
